3.2 - LTE 4G RAN ARCHITECTURE - eUMTS - INTRODUCTION

LTE 4G RAN ARCHITECTURE - eUMTS - INTRODUCTION In previous Generations, the base stations were controlled by a central device. In 2G, it was the base station controller, and in 3G it was the RNC. In LTE, this concept was abandoned, as it required significant resources, because the task was concentrated in few network nodes. Most applications on the device only transmit and receive information in bursts with long timeouts in between. During these times of inactivity, the air interface connection to the mobile device has to be changed to use the available bandwidth efficiently and to reduce the power consumption of mobile devices. So The packet-switched connections generate a lot of signaling load because of the frequent switching of the air interface state. So these management task were distributed, to speed up the connection setup time and reduce the time required for handover, which is very crucial for real time services. Thus making the LTE access network a simple flat network of interconnected Base Stations without a centralized controller. Happy Learning.
